MECHANISM FOR INTERLOCKING GUN PARTS.

Specification of Letters Patent.

Patented March 31, 1908.

Application filed October 29, 1906. Serial No. 841,119.

provements are fully set forth in the following specification.

This invention relates to improvements in mechanisms commonly availed offor interlocking those parts of a gun or like fire-arm generally knownas the tang and the stock; and its object is to provide a mechanism ofthe character indicated which shall be simple and inexpensive as regardsconstruction; which shall materially enhance the efliciency anddurability of the gun or fire-arm in conjunction with which it may beused; which shall be convenient in its application to the purposes forwhich it is intended; and which shall possess certain well-definedadvantages over prior analogous mechanisms.

The invention consists in the novel com binations and details ofconstruction, hereinafter more particularly described and set forth inthe appended claims.

The invention is clearly illustrated in the accompanying drawings,wherein like reference-numerals denote corresponding parts throughoutthe respective views, and as to drawings: Figure 1 is a bottom plan viewof the front end-portion of a gun-stock with the tang applied thereto, aportion of the guard-base and trigger-plate being broken away to betterdisclose the interior details of the construction. Fig. 2 is a central,vertical, longitudinal section of the construction illustrated in Fig.1, the section being taken substantially along the line a:;c of Fig. 1.Fig. 3 is a detail view showing in perspective and detached from thegeneral construction, the removable wedge-faced bolster which I purposemaking use of.

Having reference to the accompanying drawings, 2 denotes the stock of agun or similar fire-arm, the same having a recess or chamber 3 toreceive more or less of the usual firing mechanism; 4 the tang disposedat the front end of the stock 2; and 5 the trigger plate, disposed alongthe stock 2, closing the recess 3, and secured to said stock and to thetang 1, which it overlaps at its front end, in any appropriate manner,as by means of the bolt 6 and'screw 7, respectively. The trigger-plate 5is provided at its inner side with a wedge-faced boss 8, which projectsinto the recess 3, substantially as shown; and for cooperation with saidboss, for interlocking purposes, as will hereinafter appear, I provide awedge-faced bolster 9, removably situated within the recess 3 andadapted to be engaged along its wedge face by the wedge-face of the boss8, under strain properly applied to the latter.

Heretofore the part which I term a wedgefaced bolster, has been formedintegral with the stock 2, and hence of the same material, usually, ifnot always, hard wood. When thus formed, however, it is not a rarehappening that the bolster, under the strain which must necessarily bebrought thereon in practice, and particularly if deterioration shallhave appreciably taken place in the material of which it is formed,breaks off, thereby materially weakening the relation of the assembled parts, if not rendering the fire-arm worthless for practical purposes. Iovercome this defect in prior analogous constructions, by constructingthe bolster 9 as a separate and distinct part, hence permitting itsformation of metal, or other suitable material possessing a much greaterpower of resistance than wood, and at the same time permitting saidbolster to be removed from the recess 3 and replaced therein at the willof the user.

As herein shown the bolster 9 is provided with a rearwardly projectingfoot 10, through which is formed an opening 11. The tie-bolt 12 projectsfreely through a suitable opening formed in the tang 4, a furtheropening formed in the stock 2, thence through the opening 11, formed inthe foot 10, and is threaded at its inner end to engage the threadsformed in the wall of the opening 13, with which the boss 8 is provided.Hence, the parts being assembled substantially as illustrated in Fig. 2of the drawings, it is evident that by turning the tie-bolt 12 homeward,a binding or interlocking effect is produced between the wedge-face ofthe boss 8 and the wedge-face of the bolster 9, which effect causes,through the medium of the trigger-plate 5, the tang 4 to be firmly andsecurely seated against the front end of the stock 2; and to release theparts from this interlocking effect, it will be understood that it isonly necessary to reversely turn the tiebolt 12. The parts having beenadjusted and interlocked as just described, a suitable opening is boredthrough the stock 2 to receive a bolt 6, which further aids in holdingthe several parts relatively in position for service.

The operation of the mechanism will be apparent from the foregoingdescription thereof.

It will be seen that my improved mechanism for interlocking gun-parts isparticularly well adapted for the purposes for which it is intended, andfurther that the same may be modified to some extent, particularly asregards the details of construction whereby the bolster 9 is renderedcapable of cooperating with the tie-bolt 12, without departing from thespirit and principle of my invention.

Having thus described my invention, what I claim and desire to secure byLettersPat ent, is

1. In combination with a gun-stock, a tang seated against the forwardend of said gun-stock; a trigger-plate secured to said gun-stock andoverlapping and secured to said tang, said trigger-plate being providedwith a wedge-faced boss; a removable bol-.

ster having. a wedge-face cooperating with the wedge-face of said boss;and means cooperating with said tang, whereby said boss may be adjustedin a manner to produce a binding effect on the wedge-face of saidbolster, substantially as herein specified.

2. In combination with a gun-stock having a transverse bolt opening, atrigger plate secured along said stock, sald trlggerplate having a wedgefaced boss projecting inwardly therefrom; a removable bolster having awedge-face adapted to be engaged by the wedge-face of said boss, andhaving a foot provided with an oaening; and a tiebolt projecting throughtie opening in said stock, through the opening in said foot, andthreaded at its inner end to accordingly engage said boss, substantiallyas herein specified.

3. In combination with a gun-stock, a trigger-plate having a wedge-facedboss projecting inwardly therefrom; a bolster removably situated at theinner side, and having a wedge-face engaged by the wedge-face,

of said boss and means for drawing said boss in the direction of saidbolster, substantially as herein specified.

4. A bolster for mechanism for interlocking gun-parts, the samecomprising a main portion having a wedge-face, and a foot projectingrearwardly from said main portion, said foot having an opening formedtherein, substantially as herein specified.
